Franklin-Silverman Liver Biopsy Needle 145mm

Franklin-Silverman 145mm Liver Biopsy Needle

The 145mm Franklin-Silverman is the long-shaft variant for image-guided deep-organ biopsy — typically used in CT-guided procedures targeting deep retroperitoneal masses, post-laparoscopic-surgery anatomical variations, or post-Roux-en-Y-bypass altered anatomy where standard-length biopsy needles cannot reach the target. The 14.5cm shaft provides reach without compromising the cutting-biopsy mechanism’s reliability.

The CT-guided deep-biopsy workflow

CT-guided biopsy uses real-time CT visualisation to advance the biopsy needle along a planned trajectory to the target lesion. The interventional radiologist or surgeon places the trocar through the skin, advances under CT-fluoroscopy guidance, confirms position, and performs the cutting biopsy. The 145mm Franklin-Silverman length accommodates CT-table geometry and abdominal-wall thickness that 105mm needles cannot bridge.

The complication-rate considerations

CT-guided cutting biopsy at experienced interventional-radiology centres has bleeding complication rates of 1-2% and pneumothorax rates under 1% — substantially better than the original Vim-Silverman blind-technique results, despite the longer needle. The image-guidance technological revolution explains most of this safety improvement.
